When should the "On station and all clear" report be given?

The "On station and all clear" report is crucial for ensuring safety and effective communication during operations involving amphibious vehicles like the LCAC (Landing Craft Air Cushion). This report should be given after the inbound LCAC crosses the water edge. At this point, the vehicle has successfully transitioned from water to land and is established in its designated area, allowing for operations to continue safely without the risk of additional vessel movements disrupting the situation.

Providing this report before entering the water would not be suitable, as it does not indicate that the vehicle has completed the critical transition. Reporting after all personnel are aboard is important but should occur only once the vehicle is already on land to confirm the mission's safety status. Similarly, issuing the report when the LCAC is parked on land without verifying its status following the water transition does not provide the complete context necessary for operational clarity. Thus, the correct timing for the "On station and all clear" report aligns with the successful crossing of the water edge, ensuring that all procedures related to safety are adhered to during the operation.
